Рассмотрены методы очистки воды от биологических и химических загрязнений, связанные с различными типами электрических разрядов и режимов работы. Обсуждаются достоинства и недостатки различных электроразрядных методов очистки применительно к конкретным видам загрязнений, их энергоэффективность и перспективы промышленного применения. Показано, что тип разряда в одной и той же системе может зависеть как от электротехнических параметров разрядной цепи, так и от геометрических, совокупность которых определяет характер развития разряда, что в свою очередь, влияет на особенности протекания реакций в жидкости. Обсуждается дальнейшая оптимизация этой технологии.
This paper presents advanced water purification oxidative methods capable of decomposing toxic compounds into smaller molecules with possible full mineralization up to CO2 and H2O. Electrical discharge plasma contact with water occupies a promising position among the advanced oxidation methods, since such a mechanism allows the generation of a wide range of oxidizing particles in the immediate vicinity of treated liquid. Water purification is a technology that has been extensively studied for many types of thermal and no thermal plasma, such as electro hydraulic discharges, dielectric barrier discharges (DBD), plasma corona jet, floating sliding arcs, etc. Methods of water purification from biological and chemical pollution associated with various types of electrical discharges and operating modes are considered. The advantages and disadvantages of various electrical discharge purification methods for specific types of pollution, their energy efficiency and commercial application prospects are discussed. It is shown that the type of discharge in the same system can depend both on the electrical and technical parameters of the discharge circuit and on the geometric ones, the totality of which determines the nature of discharge development that in turn affects the features of reactions course in the liquid. Further optimization of this technology is discussed, which is a very complicated task due to the large number of discharge chambers design variants, various electrode systems materials, and discharge types
